ファジィ理論による超音波診断支援システム : Analytic Hierarchy Process (AHP)を用いた推論法の最適化(一般講演2-画像診断-)  [in Japanese] Computer-assisted Diagnostic System for Ultrasonography Using Fuzzy Reasoning : Improvement of the Inference wtih Analytic Hierarchy Process (AHP)  [in Japanese]

The authors have developed the computer assisted system for ultrasonography using fuzzy reasoning. The system was constructed to differentiate the metastatic lymph node from inflammatory ones. To construct the system, we set up three fuzzy production rules according to the diagnostic criteria. Furthermore, in order to simulate the experienced clinician's consideration, we refered the method of analytic hierarchy process (AHP). Consequently, the diagnostic accuracy was improved and usefulness of the AHP was suggested.
